Department of Psychology Forensic

Chapter 111 So, Do You Want To See Me?
City Police Department.

Zhou Zheng knocked on the door lightly, then pushed the door open and walked in. He was already familiar with this place, and when he came in, he heard "Zhou Shen" being called one after another.

Hearing such a title again, he felt a little confused, and Professor Fan's voice seemed to be right next to his ears.

Does Forensics Really Affect Criminal Psychology?

A huge question mark popped up in Zhou Zheng's head. He wanted to calm down and think about it. After being busy for a while, he seemed to be driven away by the case, and he couldn't think clearly about many things.

"Team Xia."

Zhou Zheng walked quickly to Xia Yan's office, and immediately caught the latter's attention, saying, "We have information about the source of the corpse."

"what?!"

Xia Yan immediately stood up, this kind of information was really important to him, recently, he was like a headless chicken running around.

Check here, check there, consume a lot of time and energy, but in the end it has no effect.

The identity of the victim is the biggest problem in this case.

As long as the identity of the victim is confirmed, it is not far from solving the case.

"During the second autopsy, we found that the victim's left rear molar had undergone wisdom tooth extraction surgery, and there was a life reaction at the suture. Judging from the recovered form, the death time would not exceed three hours after the operation, so the victim must have been in the hospital. For the operation performed in Jianghai City, we can investigate the records of the dental clinic." Zhou Zheng said solemnly.

"Great!" Xia Yan's eyes suddenly lit up. He knew this kind of operation too well. He just needs to connect with the medical system. Now the area that can be delineated is getting smaller and smaller. ?"

"No more." Zhou Zheng shook his head.

"Thank you." Xia Yan raised his hand and patted Zhou Zheng's shoulder, then got up and shouted loudly: "Brothers, come alive!"

……

Zhou Zheng didn't know how he got back to the Forensic Medicine Center. He was thinking about Professor Fan's words all the way.

It has to be said that Professor Fan's words had a great influence on him, and he was immersed in these words. He had never thought about the problem between forensic medicine and criminal psychology before.

"The height and age of the three victims have probably been restored."

Cui Jun came out of the anatomy room, his face was full of exhaustion. There are a series of regression equations to calculate height and age through bones, but even that would be tiring to speculate.

"You write the report!"

"Master." Zhou Zheng looked up at Cui Jun, and said solemnly: "After the report is finished, is there anything else?"

"I want to go to the scene again." Cui Jun said the scene referred to the zoo, and he continued: "I just received a call that the two Siberian tigers have been transferred from the Liger and Tiger Park, and they can be inspected. Want to see if there are any missing details."

"Can I go straight to get off work?" Zhou Zheng pursed his lips and asked tentatively.

"Are you okay?" Cui Jun froze for a moment.

"Well, a little." Zhou Zheng hesitated.

"A date?" Cui Jun's eyes were burning with gossip.

"Hmm...well..." Zhou Zheng thought to himself, Professor Fan was waiting for him in the office, so this could be considered a date.

"Then go and do your work. It's okay. Just finish the report. That thing is too laborious." Cui Jun waved his hand and said, "You can leave after finishing the report. I have to rest for a while."

"Thank you, Master." Zhou Zheng grinned, but the smile was not too distracting.

"It's your vacation." Cui Jun didn't say anything more, he stretched his arms, took out a pack of cigarettes from his pocket, and walked outside.

All of a sudden, Zhou Zheng was the only one left in the forensic center, making the already quiet room even more lonely.

Zhou Zheng was sitting on a chair, looking at the camera in front of him, which recorded Cui Jun's inspection records of the three ossified and mutilated corpses. What he has to do now is to extract the steps, attach pictures, and write Conclusion, make a report, and print it out.

"call……"

Zhou Zheng took a deep breath, his mood was inexplicably complicated, and now the disturbed mind is not clear about his true thoughts. This is often the case. Even people who study psychology may have psychological problems, and often such problems When there is no one else to solve it, it is easy to go into a dead end.

He likes forensic medicine very much, and he knows this very well in his heart. From the moment he chose the forensic medicine major until now, he has never regretted it.

As for criminal psychology, when he first chose it, he had only a slight interest. Later, he got involved in it and found that the content covered a wide range, allowing him to diverge his thinking on the basis of forensic science.

but……

Let him give up forensic medicine and devote himself to the field of criminal psychology...

He still can't do it!

"Let's have a good chat with Professor Fan later!"

Zhou Zheng let go of the big stone in his heart for a while. He respected Professor Fan so much that even if it was his hobby, he didn't want to hurt Professor Fan's heart.

Immediately, he picked up the camera, turned on the video screen, adjusted to the scene when he left, and saw Cui Jun first came to the first incomplete bone.

"This corpse has only three bones, one clavicle, one femur, and one radius."

"Only the radius is relatively well preserved and can be measured."

"To measure the length of the radius, you need to measure the straight-line distance from the highest point of the radial head to the tip of the styloid process, and measure it with a pelvic disc."

Having said that, Cui Jun took out the pelvis measuring plate from the toolbox.

The measuring pelvis is a human bone measuring instrument composed of a horizontal base plate, a vertical plate, a horizontal plate, a triangular plate, a steel ring, and weights.

Cui Jun laid a piece of coordinate paper on the bottom plate of the pelvis and covered it with a glass plate to measure the radius.

When Zhou Zheng saw this, the tools that would be used in the forensic identification that he learned in school came to mind. The pelvic disc is a special instrument for measuring long bones. It can measure the length, width, neck-shaft angle, and condyle shaft of long bones. angle and so on.

In forensic identification, there are many types of instruments for measuring bones. There are 18 kinds of instruments, each of which has a specific purpose. In addition to measuring the pelvis, there are straight-foot gauges, curved-foot gauges, and round-bar straight-foot gauges. , tripod parallel gauge, tape measure, cubic cranial fixer, Morrison cranial fixer, attached protractor, simple bone tracer, level needle instrument, parallel fixed point instrument, etc...

Zhou Zheng quickly recorded the bone data measured by Cui Jun in the computer, and then brought it into the regression equation to further determine the victim's height.

Determining age and height through bones is sequential, and age must be confirmed first, because age is an important factor affecting height.

Inferred age can be judged based on the growth of specific bones, such as the pubic symphysis, or the auricular surface of the ilium, etc. However, in the absence of such bones, bone histology can also be used to infer.

As for this corpse, the age can be estimated by observing the shape of the femur.

Zhou Zheng had already thought of the regression equation in his memory.

……

Time passed by, and by the time Zhou Zheng finished writing the report, it was already time to get off work at night.

This report is like doing a volume of math problems. The numbers measured by Cui Jun are the known data, and the calculations of each equation are the required values.

"Finally done!"

Zhou Zheng stretched wearily while looking at the paper being spit out continuously from the printer.

According to the identification results, apart from the corpses in the cross-sea bridge dumping case, the other three corpses were two men and one woman.

Among them, a male is between 41 and 50 years old, and his height is around 180.

The other male is between 21-30 years old and around 190cm tall.

The female deceased was between 41 and 50 years old and about 170 tall.

These three data cannot give very specific numbers. After all, the results calculated by the regression equation only correspond to the corresponding intervals, and can only be used as a reference when checking the identity of the victim.

After Zhou Zheng printed out all these documents, he left a copy on Cui Jun's desk. When he was writing the report, Cui Jun had already appeared on the scene and was inspecting the lion and tiger garden in the zoo.

After placing the paper report on the table, he picked up the stapler on the table and pressed it on the report to avoid being disturbed by the evil wind that appeared at an unknown time.

After doing all this, he picked up another report and walked towards the criminal police team, preparing to vent the data to Xia Yan.

At the door of the criminal police office, Zhou Zheng knocked on the door lightly, then pushed the door open, only to find that there was only one person inside, lowering his head and writing something on a piece of paper.

When the man heard someone coming, he immediately looked up. When he saw that it was Zhou Zheng, his eyes lit up suddenly, and he said, "God Zhou, you are here, do you have any clues?"

"There's a report, I'll give it to you directly. You can contact Captain Xia. I have something to do, so I'm leaving first." Zhou Zheng recognized that this person was a familiar face of the criminal police team, and he handed the document in his hand to the After that, he turned and left.

……

Zhou was standing at the gate of the Municipal Bureau Building. Instead of taking the bus, he hailed a taxi and drove straight in the direction of Jianghai Medical University.

Along the way, he sat in the passenger seat, silently staring at the scenery outside the car window, not knowing what he was thinking.

Not long after, the taxi stopped at the entrance of the teaching area of ​​Jiang Medical University. Zhou Zheng got out of the car after paying, and walked towards the No. 2 teaching building where Professor Fan's office is located. There is a psychology major classroom.

At this time, it was six o'clock in the evening, and the teaching work in the teaching area had already stopped. The students had been out of school for a while, and it seemed that the teaching area was a little deserted.

Zhou Zheng went up to the 4th floor and found room 407, which is Professor Fan's office.

"Boom boom boom——"

Zhou Zheng gently knocked on the door and said, "Professor Fan, it's me, Zhou Zheng."

"Please come in." The deep and vicissitudes of life sounded through the office door, and this voice belonged to Professor Fan.

"Ok."

Zhou Zheng raised his hand to touch the doorknob, shook it lightly, then pushed the door open, and suddenly saw Professor Fan sitting behind the antique desk.

"Professor Fan, I'm here."

After Zhou Zheng entered the office, he closed the door and stood in front of the desk, looking like a student called by the teacher.

Professor Fan remained as still as a mountain, focusing his eyes on the book in his hand, patiently reading word by word, until he finished reading this page, he just took out the feather bookmark beside the table, picked it up and put it on the table.

The moment the book was closed, Zhou Zheng saw the title of the book - "Abnormal Psychology".

"Zhou Zheng, what do you think of criminal psychologists?" Professor Fan said straight to the point, and didn't ask Zhou Zheng to sit down before he spoke.

"Criminal psychologists can keenly use the traces and clues left on the murder scene and the victim to infer the psychology of the murderer when he committed the crime, so as to find the labels on them, narrow the search scope, and help solve the case." Zhou Zheng replied.

"Do you think the psychology of guessing the murderer..." Professor Fan pushed the slightly yellowed glasses on the bridge of his nose, and said, "Do you rely on instinct and intuition?"

"No!" Zhou Zheng shook his head immediately and said, "It depends on the data model!"

"Zhou Zheng, what you said is right and wrong." Professor Fan's eyes focused on Zhou Zheng's body through the lens, and his eyes instantly became much sharper, and said: "Criminal profiling does require the support of data models, but intuition is more important. This is why criminal psychologists are so scarce, and the vast majority of people don’t have this sense of smell. To make an inappropriate analogy, training police dogs also requires screening breeds in advance, not just any dog.”

"Yeah." Zhou Zheng nodded silently. He probably guessed what Professor Fan was going to say next. Instead of speaking, he waited for Professor Fan's words.

"You haven't seen Wang Fan yet, have you?" Professor Fan suddenly changed the topic and brought the topic to another place.

"I haven't been there." Zhou Zheng shook his head. When he heard the name Wang Fan, that haggard figure appeared in his mind. The last time we met, we were still in the interrogation room. Wang Fan admitted that after He was sent for inspection, and was never seen again.

"According to the information I got, his case will be tried soon, I think you should talk to him." Professor Fan continued: "We criminal psychologists can't close the door and imagine out of thin air. Many murderers are psychologically abnormal. It is unimaginable for normal people. In order to keep our sense of smell sharp and accumulate more crime experience, we need to often chat with criminals to explore the real world in their hearts."

"I don't have permission to see it!" Zhou Zheng said helplessly. Now that he is a small forensic doctor, how could he meet a quasi-death prisoner.

"As long as you want, I can help you find a way, but I must tell you that this is a very important step." Professor Fan stared at Zhou Zheng, and asked in a deep voice: "So, do you want to see me? "
